Actually, it was first answered by Larry Niven. Dave posted the essay here.



The Doctor is correct.

In fact, that essay has been mentioned here multiple times, for example:

Not to mention the film Mallrats:

    Lois could never have Superman's baby. Do you think her fallopian tubes could handle the sperm? I guarantee he blows a load like a shotgun right through her back. What about her womb? Do you think it's strong enough to carry his child? He's an alien for Christ sake! His kryptonian biological makeup is enhanced by Earth's yellow sun. If Lois gets a tan, the kid could kick right through her stomach. Only someone like Wonder Woman has a strong enough uterus to carry his kid. The only way he could bang regular chicks is with a kryptonite condom . . . that would kill them.
